They’re not meant to take those side impacts like that and when they do, it crushes into the passenger compartment,”said Sgt.

West admitted to having four alcoholic drinks earlier in the night. Court documents said his BAC varied from 0.10 at the scene to .08 in a blood test. He also showed signs of impairment in four out of six field sobriety tests.
